PORTLAND, Ore. (KOIN) — Opening statements were presented Monday in the murder trial of a man accused of shooting his brother.

Mickey Omega Rolin is charged with one count of murder with a firearm constituting domestic violence. He was arrested in late December 2013. According to Portland Police, officers responded to reports of a domestic disturbance and shooting on Dec. 24, 2013.

When officers arrived on the 3600 block of Southeast 67th Avenue, they reportedly saw Mickey Omega Rolin walking out of the backyard. Mickey Omega Rolin had a white shirt with blood on the front and was allegedly holding a white, bloody rag over his mouth, prosecutors said.

Police asked Mickey Omega Rolin what happened and he reportedly said he was asleep in the basement when he was attacked by someone he didn’t know, court documents state. Police searched the home and found 61-year-old Terry Lee Rolin dead.

A neighbor told police he was outside smoking just before the shooting occurred. Moments after, he said he heard a family member run outside yelling, “My uncle shot my other uncle, my uncle shot my other uncle,” prosecutors said. The neighbor reportedly grabbed his phone and went into the Rolin residence where he found Terry Lee Rolin on the ground. The neighbor told emergency dispatchers Terry Lee Rolin appeared to have been shot in the head, prosecutors said.

Mickey Omega Rolin’s defense attorney, Russell S. Barnett, III, P.C., said he expects to show the jury inconsistencies with statements made by Terry Dustin Rolin. Barnett also said homicide detectives failed to follow up on several leads. The reason Mickey Omega Rolin is photographed in a wheelchair with facial injuries is because he was assaulted by his brother Terry Dustin Rolin, Barnett said.

Homicide detectives found a handgun in a neighbor’s yard. The home is directly behind the Rolin household, court documents state. Police confirm the 5-shot revolver had been fired two times, prosecutors said.

Mickey Omega Rolin, originally from Bakersfield, California, has been convicted of 9 felonies, one misdemeanor and 2 probation violations, according to court records.

The murder trial is being heard before Judge Kenneth R. Walker and is scheduled to last until July 2.
